Advancing science in the Arctic is crucial to understanding global climate dynamics, supporting policy decisions, and managing nationally and internationally important resources. In coordination with the Interagency Arctic Research Policy Committee (IARPC) and USGEO, USGCRP member agencies observe and monitor the Arctic environment to understand the impacts of global change on this ecologically, culturally, and economically significant region. Polar orbiting satellites provide data that are combined with information from surface-based measurement networks, airborne and

Since 1989, the U.S. Global Change Research Program (USGCRP) has submitted annual reports to Congress called Our Changing Planet. The reports describe the status of USGCRP research activities, provide progress updates, and document recent accomplishments
In particular, Our Changing Planet highlights progress and accomplishments in interagency activities. These highlights represent the broad spectrum of USGCRP activities that extend from Earth system observations, modeling, and fundamental research through synthesis and assessment, decision support, education, and public engagement.

The continual cycling of carbon through the atmosphere, oceans, soil, and living organisms is an essential function of the Earth system. The U.S. Carbon Cycle Science Program (under the auspices of USGCRP; carboncyclescience.us) and USGCRP agencies are working to understand how climate change and human activities are altering this foundational component of the environment, and how these alterations feed back to affect climate change. Some examples are highlighted below:
At least two thirds of the world’s land-based organic carbon is stored in

Agricultural production is a critical sector of the domestic and global economy that is affected directly by climate change. The Agricultural Model Intercomparison and Improvement Project (AgMIP)—supported in part by DOE, NASA, USAID, and USDA—is a major international effort linking the climate, crop, and economic modeling communities to produce improved projections of climate impacts on the agricultural sector, thereby enhancing capacity to prepare for and respond to these climate-driven changes.

“Indicators” are variables that can be used to measure the status or trend of a system. Indicators of climate-related global change—whether ecological, physical, or societal—can be used to track and communicate key aspects of the changing environment, point out vulnerabilities, and inform decision making at local, state, and national levels.
A pilot set of climate indicators is being developed collaboratively by USGCRP agencies including NASA, NOAA, EPA, USDA, DOE, DOD’s U.S. Army Corps of Engineers (USACE), CDC, and DOI. The

Drought is a significant hazard for the United States, with potentially severe and long-lasting impacts on the Nation’s economy and food and water supplies. USGCRP agencies are advancing our understanding of the causes and consequences of drought, an FY 2015 interagency research priority (see Section 4). They are also collaborating in efforts to support drought preparedness and recovery, such as the National Drought Resilience Partnership (a deliverable of the President’s Climate Action Plan) and the National Integrated Drought Information System (NIDIS).

Overview
Climate and Earth system modeling supported by USGCRP agencies such as DOE, NASA, NOAA, NSF, and others was foundational to the IPCC’s Fifth Assessment Report (AR5) on the scientific basis for climate-change, released in 2013. Along with international partners, Federal and Federally supported modeling centers

Overview
Indicators are measurements or calculations that represent the status, trend, or performance of a system (e.g., the economy, agriculture, air quality). USGCRP, with the participation of 9 of its 13 member agencies—NOAA, NASA, EPA, USDA, DOE, DOD’s U.S. Army Corps of Engineers (USACE), HHS’s

Overview
The 2011–2012 U.S. drought was the most severe and extensive in at least 25 years, and the effects are still being felt in some areas of the Nation. Recently, USDA partnered with local governments, colleges, and state and Federal partners— including NOAA and FEMA—to conduct a series of regional drought workshops. Hundreds of farmers, ranchers, business owners, and other stakeholders met with government officials to discuss needs
